This document provides an overview of VMware vSphere Install, Configure, Manage (ICM) certification and virtual machine concepts. It discusses the architectural differences between traditional, host-based, and bare-metal architectures. It also describes the benefits of using virtual machines such as easy relocation, easy management, and ability to support legacy applications. Additionally, it outlines the process for creating a virtual machine including pre-implementation steps, implementation procedure, and post-implementation steps. Finally, it lists some tasks for the lab including creating a VM, installing guest operating systems, and installing VMware tools.

Benefits of Using Virtual Machines Physical Machines Virtual Machines Difficult to relocate: Moves require downtime. Specific to physical hardware. Difficult to manage: Require physical maintenance. Hardware failures cause downtime. Hardware has limitations: Hardware changes limit application support. One-to-one relationship between application and server. Easy to relocate: • Encapsulated into files. • Independent of physical hardware. Easy to manage: • Isolated from other virtual machines. • Insulated from hardware changes. Provide the ability to support legacy applications. Enable servers to be consolidated. Physical Machines
